Abstract
Berberine, a natural cationic dye with excellent antibacterial activity, was extracted from the roots of Berberis vulgaris
and applied on cotton fabric. Naturally, there is no affinity of cationic dyes for cotton fiber. To improve the dyeability
of cotton fiber, plasma treatment and acrylic acid grafting, using plasma technology for pretreatment, were employed.
The grafting of acrylic acid was confirmed using ATR-FTIR. The effect of pretreatments on the dyeability of cotton
was evaluated. The antibacterial activity of the dyed samples was evaluated according to AATCC test method 100-
2004. The samples dyed after acrylic acid grafting showed the highest antibacterial activity.
